The Internet was conceived as a medium to efficiently enable point-to-point conversations. However, the main source of Internet traffic today is easily duplicable and location-independent content. In this talk we will focus on three aspects of latency and costs for P2P-assisted content distribution using analytical models supported by real-world measurements.

Our first focus in this talk is on utilizing awareness of demand for a piece of content in the interest of efficient resource usage. Suppose that we can use a centralized server and/or a P2P network for content distribution. What would the latency experienced by users look like? We use the Bass model of demand evolution to compare a hybrid of peer-to-peer and a centralized client-server approach against each method acting alone. Can we determine how to combine server and P2P methods so as to minimize the latency experienced by users while maintaining low server utilization?

In the second we focus on developing ISP-friendly P2P content distribution. P2P content distribution often increases transit cost to Internet Service Providers (ISPs), as peers exchange large amounts of traf?c across ISP boundaries. This ISP oblivious behavior has resulted in misalignment of incentives between P2P networks—that seek to maximize user quality—and ISPs—that would seek to minimize costs. Can we design a P2P overlay that accounts for both ISP costs as well as quality of service, and attains a desired tradeoff between the two?

In the third we briefly consider the use of P2P networks for real-time streaming. In such P2P streaming systems, each peer maintains a playout buffer of content chunks which it attempts to ?ll by contacting other peers in the network. The objective is to ensure that the chunk to be played out is available with high probability while keeping the buffer size small. Our question is: Can we determine a policy that minimizes the buffer size for a given target probability of skip-free playout?

Check your private info

Ever wonder what personal information is transmitted across the net when you browse? On todays' Tekzilla Daily, Veronica shows you a helpful website that will show you exactly which pieces of data are exposed.

In this session we will discuss the specific challenges of using the Maps API to create content targeted at the mobile audience. Topics will include: devices round up, mobile networking primer, strategies to deal with latency, display and user input constrains.

The Google Search Appliance is an on-premise hardware and software solution that brings Google search into the enterprise, so users can find content quickly and securely. In this session, learn how partners today are plugging enterprise data sources into the GSA through Connectors and displaying results using OneBox.

The old OpenDNS Stats system was built when we were doing 1 billion queries a day and had far outlived its usefulness. Playing hot potato with load on overworked servers all struggling to keep up gets old after a while, doesn’t it? This gave me the opportunity to start from a blank slate and build the system we need to serve us at 8 billion queries a day and scale to 16 or 24 billion. We considered writing another set ofPHP shell scripts, we considered working with Hadoop and we considered non-MySQL data storage options. I’ll explain why, in the end, I chose a custom map-reduce-esque implementation in PHP and C++, using MySQL for persistant storage.

While I’m proud that my initial design withstood the test of implementation, there were of course false starts and wrong turns. In the talk I’ll detail three problems and the solutions that got me to production.

False start #1: my new-guy lack of understanding of the old system combined with my starry-eyed desire to use some new technology (Thrift in this case). Hoping to reduce disk I/O concerns, I started throwing log files around line-by-line using a Thrift service. The results were massive network congestion and a more difficult path to failure recovery.

False start #2: I’ll go through another case of small software design tweaks making a huge difference in MySQL performance when tuning InnoDB isn’t enough.

False start #3: When you’re aggregating anything in memory, you’ve got to expect std::bad_alloc to come around eventually. At first, I tried to tally memory usage and proactively free some when necessary but found this to be inaccurate and crash-prone. The production version can gracefully handle these memory exceptions without data loss.

After the tour of some of the implementation challenges, I’ll walk through the architecture of the entire production system from DNS servers through the map-reduce pipeline to databases and onto the website for all of our users. I’ll also share some of the (less common) tools I found indispensible.

On May 5 and 6, 2009, in Mountain View, we brought together Googlers and leaders from academia and the corporate world for a 2-day summit to discuss the state of the global Internet. The goal of the summit was to collect a wide range of knowledge to inform Google's future plans--from product development and market reach to users' expectations and our ability to keep the Internet open yet secure.

More than 30 speakers and moderators led discussions around 8 topics: Networks; Wireless and Sensor Technologies; Security; Standards; Applications; Democracy, Law, Policy and Regulation; Search and Cloud Computing; and The Future. Eric Schmidt, who offered some remarks, expressed optimism that the challenges we face with governments' walling off access to the Internet can be overcome technologically by building networks that are transparent, scalable, and open.

Want access to your files stored at home? How about hosting a home web server? Static IPs are expensive, if you can even get one. We set up Dynamic DNS instead!

'Back in the day' if you wanted to run a web server, email server, or FTP server from home you needed a static IP... and they often added quite a bit to the monthly bill from your ISP.

Dynamic DNS, however, lets you use a DHCP assigned address -the kind you probably have at home- just like a static IP address. That means if you have a broadband connection and sign up for a free account at DynDNS you can run a website or FTP server straight from your home.

We show you how to set it up on this episode of Systm, along with a quick and easy way to share files you and your friends can access through any browser: HFS, the HTTP File Server!

Dealing with domains and hosting and all the server setup stuff isn’t usually the most comfortable stuff for web designers. In this screencast I walk though my regular process and share many little tips of how I like to handle it. I use a real live domain name that I recently purchased on Go Daddy, point it to my Media Temple hosting and then switch the email handling to Google Apps.

An MMORPG project is challenging for any development team, let alone a distributed team of "amateur" volunteers. This talk will explore the internal design of the FOSS MMO project called PlaneShift, and how that design was influenced by the strengths and weaknesses of the team structure and the community. Topics will include server design, network topology, NPC AI and management and player security, among others.

Speaker: Keith Fulton
Keith Fulton is the CTO at ChoicePay, Inc. in Tulsa, Oklahoma which is an electronic payments company. In his spare time, he has been the principal architect on the PlaneShift project since 2001, along with dozens of other contributors. PlaneShift has over 500,000 registered accounts and maintains a small, tight-knit community of players, fans and developers. The game is entirely written in C++ under the GPL.

Social interaction has become implicitly expected of modern web-based applications. Desktop applications, however, have yet to overcome the technical barriers of peer discovery and message passing without the use of centralized servers. This session explores common peer discovery paradigms, examples of peer-aware Ruby application code using the Journeta P2P LAN library, and approaches to overcome common architectural issues of distributed event-driven systems.

Why is route calculation done at both layers 2 and 3 of networking? Is one better? Do we need both? This talk explains the historical accident by which bridging was conceived and the properties that make it attractive, as well as dangerous, today. The talk discusses new work being done in IETF known as TRILL (TRansparent Interconnection of Lots of Links), which combines the advantages of bridges (layer 2 forwarding devices) and routers (layer 3 forwarding devices). Although the basic idea is fairly simple, certain properties of bridges, such as their ability to create partitioned VLANs on a layer 2 cloud, make the design challenging.

Speaker: Radia Perlman
Dr. Radia Perlman is a Fellow at Sun Microsystems, working on network and security protocols. She invented many of the basic algorithms that make today's network infrastructure robust and scalable. Her current research interests include assured delete, making large networks robust against Byzantine failures, and replacing bridges/switch with technology which is upwardly compatible, but more robust, flexible, and scalable. She is author of "Interconnections: Bridges, Routers, Switches, and Internetworking Protocols", and coauthor of "Network Security: Private Communication in a Public World", which are widely used both as textbooks in universities and for engineers to learn the field.

History has shown that access to the internet advances many facets of life including education, economic growth, and health care. Currently, only approximately 20 percent of the world population has access to the internet, which is mainly focused in North America, Australia, and Europe. More specifically, Africa being the most unconnected continent in the world has only 5 percent of its population utilizing the internet, whereas 70 percent of the population uses the internet in North America. It is predicted that these unconnected areas of the world will soon be serviced via land lines in the coming decades. However, no short term solution to this problem currently exists. The students from the Space Systems Engineering program at the University of Michigan have worked on designing a low-cost system that fulfills this "gap" in internet connectivity. This presentation will focus on their proposed solution to delivering such capabilities to the rural populations of Africa. In addition, upcoming technologies will be discussed that will impact similar missions in the future.

Veronica is traveling for her day job, so our buddy Garnett Lee, the Executive Editor of 1Up.com is here to help out!

Tom needs help finding cover art that isn't on iTunes, especially for the DVDs he's ripped for use on his iPhone and Apple TV. We haven't found an automated program we love for OS X... though we have been playing around with TuneUp Media and MediaMonkey on Windows. You could try Album Cover Finder 6.5 on the Mac... or Album Art Thingy 1.9. Frankly, Patrick still thinks going manual is the way to go, even if it takes forever!

Angel in DC plans on spending $3000 to $4000 on a gaming PC and wants to know what offers the best bang for his buck. Frankly, we're not sure a $4000 gaming machine is worth the money!

Zachary's looking at a $700 Dell Inspiron 518, and he's got a choice between a Quad Core with integrated graphics and a Dual Core with a Radeon HD 3450 for the cash. We help him decide what to buy.

Do us a favor and order it online at www.braintoniq.com. If you use the coupon code R3 you'll get a discount, and you'll help support Tekzilla!

This week's Freebie download pick is inSSIDer, an open source WiFi network scanner that runs on XP and Vista. We've spent a lot of time with NetStumbler, but this one is our new favorite for troubleshooting WiFi installs and tracking down open WAPs when we're out and about.

The easiest way to capture gameplay from the Xbox 360 and the PS3? Kieran from Ireland wants to start a video gaming show. He's also looking for a how-to on homebrewing a PSP!

Garnett's favorite tool for capturing video into Final Cut and Premiere is BlackMagic's Intensity.

Alexander's Dad wants to play PC games on an old PowerMac G4 over a network! It's probably easier to move your gaming machine, but you can try out Microsoft's Remote Desktop Connection Client for Mac 2... or something like Q emulator, which will let you run an older version of Windows on that Mac. You won't be playing any 3D games, but 'time waster' style games should work just fine!

This week's "Website We Just Can't Get Enough of!" is a classic: Homestar Runner Dot Com, the world of Strong Badia, Population: Tire, where you'll meet HomeStar Runner, Strong Bad, Marzipan, The Cheat, and the rest of the gang. Just try to get past the legendary Strong Bad Emails!

DirecTV DVR help: What are the USB, Ethernet and eSATA ports for? Randy wants more storage on his DVR!

"Is there a way to password protect folders in Windows Vista without using a separate program." You're looking for BitLocker Drive Encryption, Shaun, but it only comes in Vista Ultimate, Vista Enterprise, or Windows Server 2008. If you don't have one of those versions of Vista, we'd use TruCrypt instead.

No, matter what you see in this cartoon Veronica doesn't "poop flowers, fart summer breezes and burp rainbows." Props to COMMISIONEDcomic for the fabulous strip!

If you're thinking about buying a new PC... and you're looking for the Fastest Processor Evah... hold off until Intel's Core i7 CPU is an option! Loyd Case has a great Core i7 writeup over at ExtremeTech.com

Yup, Circuit City is closing down 155 stores... one lesson from the CompUSA liquidation: bring somebody with a cell phone that can check prices before you buy!

Last week we told you about Orb.com, our fave tool for streaming audio and video from a computer at home to anywhere -and just about anything- you can get a net connection... and we got a zillion emails asking why we didn't suggest Simplify Media, which stream audio from Windows, OS X and Linux machines to another computer or iPhone.

With all the online availability of basically ANY TV content, is this the end of set-top DVR boxes like TiVo dead? No, Matt, they aren't dead yet... at least not for Veronica and Patrick... there's still a lot of great TV out there that's tough to find on the web.

Freebie Download Pick! This week's pick is Everything, a "...fast folder and file name search engine for Windows." Searches that used to take minutes will take seconds, it's a tiny app that doesn't suck down resources, and best of all, it's easy to use!

InvisibleSHIELD? Sure, Joseph, Patrick loves 'em for screen protection on his iPhone and just about anything else with a scren, tho, like many Tekzilla viewers, he's not so happy with their full wraps.

Want to spend a bit less on your screen protection? Last time Patrick mentioned invisibleSHIELD on Twitter he got a flood of tweets about BestSkinsEver.com. They claim to use the same material, and while they don't offer a the same lifetime guarrantee they charge a -lot- less than Zagg does! Think $15 for the invisibleSHIELD face cover vs. $5.99 from BestSkinsEver.

If you only need mobile Internet access for a few weeks, you could rent an EVDO modem from Rovair, Dana, instead signing up for 2 years. Thanks for the tip on wireless Internet rentals, Greg!

This week's "Website We Just Can't Get Enough of" is WorldPress.org, a site that gathers news stories from various national and international press outlets from around the globe, from grass roots state-run news agencies. Chances are you won't find these stories at your local news stand... or news channel!

Lewis wants some options for hosting his podcast, "and also if there are any free options to start with, before moving to a paid service." Veronica loved this question, Lewis... it's her experience running her Sword and Laser sci-fi book club podcast production showing!

SpinXpress is a free program that helps you to upload your media and give it all the right attributes, Lewis, like creative commons licensing, tags, and descriptions.

If you'd like a little more reliability than a free site (mostly it's waiting to upload your files, not the actual hosting that's a problem) but don't want to pay an arm and a leg, check out Libsyn, since they offer free badnwidth, you just pay based on the amount of space you need.

Then check out Squarespace, it's powerful enough to run a retail website, but incredibly easy to work with. Signup using the code Tekzilla and you'll get 10% off for the lifetime of your membership!

DVI-D and DVI-I... why are there two? Well, Nate, nobody but the Digital Display Working Group really knows why they came up with a digital only connection (DVI-D) along with a digital and analog connection (DVI-I), but we can say that getting VGA from DVI-D is a major pain.

Steve needs a cheap component video switch so he can connect his Xbox 360 and his PS3 to the TV...

Faster internet: Tony wants to know if he should move to FiOS now, or wait for his cable Internet provider to upgrade. FiOS now vs. DOCSIS 3 someday... we say check to see if you can get FiOS now!

Want to get a Kindle on the cheap? According to PCMag.com, you'll get a $50 discount of use the code "OPRAHWINFREY" by November 1st!

Want to watch podcasts directly on your TV? We have lots of ideas for you, David!

Warren's looking for a way to stream his audio collection from home when he travels, whether it's to the office, or to an Internet connection much farther away. If you've got a PC, then you should check out Orb. You download it to your computer, and then select the kind of media that you want to share with yourself (or others) on the go. It's free, and you can stream to almost anything: a Mac, a phone, or even a gaming console.

But there are other options, such as Jinzora and Avvenu. Jinzora is a bit more complicated, because you're actually setting up a home web server. Avvenu enables you to stream your library to your Windows Mobile smartphone.

This week's Freebie Download Pick: VirtuaWin. Do you feel like you're running out of available desktop space in Windows? Do you envy OS X's Spaces or Linux's multi- console function? VirtuaWin is an open source tool that allows you create multiple virtual desktops that allow you to expand your desktop as much as you need.

"I am about to take a 10,000+ mile road trip around the U.S. I would like to have internet access wherever I go. Which service has the fastest connection and best coverage - AT&T, Verizon, or Sprint." Sounds, epic, Erik, we've got a reccos for you... and watch out: if you go over 5GB of downloads, it could get VERY expensive.

How much video RAM do you need when you're upgrading your video card? Honestly, Anthony your issues will resolve more around the GPU (Graphics Processing Unit) you pick, since that will determine your VRAM size and type!

Website We Just Can't Get Enough of!" This week's pick is PrintWhatYouLike.com! This site helps you to take the web page you want to print, and modify it to just have what you want on paper. This is great, especially when there's no printer-ready version. No more being stuck with three pages of full-color ads and other crap that you don't need!

Yi emailed from Jakarta... he's giving a thumbs up for the Asus Eee Box as a do it all home server and says: I use it for BitTorrent, http downloads, hamachi, as an FTP server, and even run Folding@Home on it" and adds "I love it. It's cheap, very quiet, don't take much space, and it comes with 2 years warranty!" Thanks for the info, Yi!

We got a dogpile of responses on Ethan's search for a new router. They can pretty much be sorted into three piles. The biggest pile said get a router than can run DD-WRT or the Tomato firmware.

A much smaller pile said build a router out of an old PC... SmoothWall, M0n0Wall, Untangle and the Astaro Security Gateway each had their fans.

The smallest pile -two letters- suggested a pair of routers. Jamal says the Linksys WRT600N Wireless-N Gigabit Router with Storage Link if money is no object, while Clark wrote in to say the Apple Airport Extreme is worth the apple tax!

JD's having mysterious problems running 3D programs like 3DS Max and Maya in Vista! The good news it's not a refresh rate issue... the bad news is you might have to update both programs... here's a like from Autodesk on how to implement workarounds for some of your problems.

This week's Freebie download pick, MKN TaskExplorer 5, comes from our very own intern Daniel Fukuba... MKN TaskExplorer 5 turns the Windows Task Manger up a notch, providing detailed info about each process, including performance and memory graphs, DLLs loaded, threads, and access token... it provides intuitive graphs showing not only the CPU usage history, but it's Kernel time and DCP time as well. It's got widgets, and power users will love it!

Will an Eee Box have enough power to run a BitTorrent program, share files and play video? Yes, Donavan!

What's the best way to hook up a new computer to an Standard Def TV? Most newer products pretty much ignore SDTV...

Speaking of SDTV, getting NTSC TV, aka regular old analog cable into an HDTV with no S-video input is a pain!

You could spend $700 on something like an ATV-3900 video up-converter, which will take the input from your TV and output it to HDMI... if you don't mind leaving your PC on, you might want to try a TV tuner for the PC itself, like one of the Elgato devices, or a WinTV. And they'll run well under $200!

This week's "Website We Just Can't Get Enough Of" is OC remix dot com ... a website dedicated to showcasing custom arrangements and remixed versions of your favorite video game music. This non profit site was created by David Lloyd, AKA DJ Pretzels, as a place to the appreciate, preserve, and interpret the different styles of video game music.

Matt in Bayonne emails, "I'm a little stumped on universal remote controls. I would love to find one that will power all of my units, including my HD projector, HD DVR cable box, surround sound and a PS3 for Blu-ray"

Patrick's a big fan of Logitech's Harmony remotes... the new Harmony One gets the most attention, but the 720 comes in around 60 bucks cheaper... $130 at Amazon, and has most o' the features, including the nifty color LCD screen.

Adding a PS3 to a universal remote is a pain... it uses a Bluetooth based remote control. Tekzilla viewers have nothing but love for the IR2BT and Nyko PS3 adapters... OK, nothing but love and one gripe. You won't be able to power the PS3 on and off, or couldn't last I heard.

Ethan's looking for a new wireless router to replace the one that cam with his FiOS install... he could build a Windsurfer parabolic booster and slip it over the nubby antennas on the back of the router. (Amazing what they did for WiFi in Patrick's old house.)

You could also build a IPCop box from an old PC. If Verizon gave you a router compatible w/ the Tomato firmware, we'd install that... yo ucan learn more about installing the Tomtato firmware on episode 71 of Systm.

We'd love to hear what everybody in the Tekzilla crew is using/wish they were upgrading to on the wireless router front... please email your faves to tekzilla@revision3.com... and put 'router recco' in the subject line!

Any suggestions for an open source replace for Microsoft Money or Quicken? Veronica sure does, Stephen!

Check out "GnuCash", "jGnash" and "KMyMoney". If you've already been working with Quicken or MS Money, and want to import files to one of these programs, you have to make sure that they support QIF and OFX formats.

Alternately, you can get "on the cloud" with online money managers, like Mint.com or the newly free Quicken Online.

CNET's Lori Grunin helps us answer your tough digital camera questions. Can too much RAM slow your PC? A free utility that lets you run Windows from a CD. Domain forwarding 101. Which is the better media PC: Xbox 360 or HTPC?

With Patrick out on vacation 1up.com's executive editor, Garnett Lee stopped by to keep Veronica company on this episode of Tekzilla.

We got a lot of users who wanted to share their solutions to the multi-monitor/KVM question we had last week. A great many of you wrote in about Synergy and its remote desktop interface allowing you to control a number of machines with a single keyboard, mouse and monitor.

Looking for a Windows rescue disk that actually runs Windows? Then check out BartPE. This emergency boot disc creation tool not only lets you run Windows off a CD, but with plugins, also adds any user installed software apps.

Joe had a question about picking a home media center. Should he go with an Xbox 360 or just roll with a HTPC? Garnett had some pretty astute observations about each, and threw in some additional points about gaming with either one.

Frank had a peculiar problem with his system. When he added 2GB of RAM to his system to bring up the total RAM size to 4GB, it got slower. What's up with that!? More RAM = slower system speed? Veronica and Garnett explore the possible culprits.

We got CNET's Lori Grunin on to talk digital cameras, specifically the digital camera questions we asked you to send in. So if you wanna see if your question got picked or just want to know more about digital cameras, check out Veronica's one-on-one with CNET's digital camera expert.

Kwang had a question about forwarding multiple domains to the same address and a further question about the difference between an A record and C name.

The final question was from David who wanted to know about getting the best sound out of a Mac Mini so that all the expensive audio playback equipment he has can be used to the fullest.

NAS vs. FTP. AngryAliens. What's the best way to use headphones with your to your PS3 or Xbox? TeraCopy moves files faster. How many screen can you attach to your monitor? Can I use a Solid State Disk in place of RAM?

iTunes 8, New Nanos, New iPhone software... Apple's made a few announcements the morning we taped the show.

Think Comcast's new 250GB cap is low? Viewers from around the world emailed to tell us they live with 50-60GB caps!

SpinRite! We received a few dozen responses to answers we gave on last week's question about burning in hard drives... pretty much all of 'em said Hey! Why didn't you recommend SpinRite???

Freebie Download Pick: TeraCopy. Greg sent this idea in and said, "TeraCopy is a great program that speeds up the copying of files on Windows. Perfect for moving music to an external drive!"

More than a few of you have been clamoring for a review of Axiotron's Modbook... the Macbook that's been converted to work like a Tablet PC. We've got the review on the show!

The New Nano goes back to 1st/2nd gen form factor (no more fatty nano!), adds the accelerometer from the Touch/iPhone for shake to shuffle... 24 hours music, 802.11b/g networking, a built in speaker... starts at $149 for 8GB.

Nick's looking to use headphones with his PS3, which, of course, doesn't have a headphone jack. We go over his options, which will work with the Xbox 360, too!

Want to send us a video question? All you need to do is record yourself in front a video camera asking a question no longer than 15 seconds. Then up load them to YouTube, and email us the link with "Video Question" in the subject line. No attachments, please!

This week's "Website We Just Can't Get Enough of" is Veronica's new fave time killer: AngryAlien.com. You won't actually find very many "angry aliens" here, but what you will find bunny rabbits, as they reenact (in 30 seconds) some of our favorite movies from Fight Club to Jaws, Goodfellas to Jurassic Park!

Bastiaan in Belgium wants some help adding more screens to his monitor. From extra cards to USB video adapters, we've got some ideas for him... and, yes, you can control muliple computers with one keyboard and mouse. You just need a KVM switch!

What's the difference between a NAS server and vanilla FTP server? We'll tell you all about it on the show, Trey!

Isn't an SSD just as fast as the RAM in your computer? If so, why do you need RAM in a computer that has an SSD for storage? Fun question, Joe... there are some big differences between the RAM in an solid state disk and the ram your CPU uses to run your OS and applications!

Jon's 22 inch monitor has an HDMI port... can he use it with his PS3? Sure, if it supports HDCP, the copy protection built into pretty much everything designed to play Blu-ray disks.

Veronica is running wild in Utah this week, so we brought in our buddy Garnett Lee from 1up.com to bring his special blend of gaming joy...

Garnett's the Executive Editor over at 1up.com... a particularly fabulous gaming review, preview and, well, all around gaming website... he gives us a heads up on the titles that he's playing right now.

Benchmarking? We give you benchmarking results of the long awaited benchmark numbers from our Nvidia Bad Ass Gaming PC.

Eee PC 901 with the Atom processor? Elliot out in Glendale is getting 5 hours with Ubuntu and -no- power management. Excellent! (Tho it might be the battery size more than the Atom processor that's bringing the long battery life. Thanks for the heads up!

Freebie Download Pick: Wiki Taxi, which lets you access the full contents of Wikipedia without an Internet connection. It's Windows only, the abridged Wikipedia database takes up 25 MB... the full, up-to-date version of Wikipedia is 8.5GB!

Patrick in Kansas wants to know if connecting to the Internet via a 3G card is risky. Truth is, it's probably safer than your connection at work, but every Internet Connection has it share of risks; all you need to do is download something from a nasty website. Run a firewall like Comodo and good anti-virus/anti-spyware!

Lincoln sent in a video question; he's looking for a good free solution to convert his videos into something his PS3 can play. Garnett recommends Video 9 for transcoding video, and he's got ideas on how to get the video to your PS3, from thumbdrive thru Ethernet, powerline and WFi.

Hot tip: Start off with a small clip to tweak settings before you to commit to larger video. You'll find out if your video looks good in minutes instead of hours!

This week's "Website We Just Can't Get Enough Of" is Ikea Hacker, a site that archives user submitted projects that show you how to re-purpose and Mac Gyver many of Ikea's products in a variety of different ways. For example, the tv unit that was converted into a terrarium, or the photography light tent made from a trash can. There's tons of material here to inspire you, check it out!

Benchmarking our Badass 3D Gaming PC: we look at 3DMark Vantage and Crysis! We're hoping to run some dual core vs. quad core and memory benchmarks before we ship this puppy out to its lucky winner.

Our Netflix sponsored Movie Pick of the Week is WarGames... as Tekzilla viewer but you can get a free trial by signing up at today www.netflix.com/tekzilla Maurice. He writes: I have a Dell XPS 420 with 4GB of RAM, a Q6600 processer, one optical drive and three hard drives. It only has a 375 watt power supply. I would love to upgrade the graphics card to an ATI 4850 to do some gaming. Does my machine have enough juice to handle it? Will removing some of the hard drives help? If not, is the power supply a standard one that I can switch out?

Maurice wants some help picking a good power supply for his gaming PC... and he's wondering how big a power supply he needs... new 3D graphics GPUs and multiple hard drives = big power supplies, especially if you want to 'futureproof' your purchase.

PS: Don't skimp on your power supply!

Do you need a switch for a half dozen computers at home, Mark? Probably not, but Ethernet switches deliver better performance than hubs, and, well, they're cheap. In fact, hubs are getting hard to find on the shelves of our local computers stores... when you can find 'em, they're cheaper as dirt.

Ben has an arcade with 17 XBox 360s... and lightning zapped the local power... "when we turned them back on they all had a red ring, but only one stopped working for good. So was that a different kind of red ring? Please tell me i don't have to replace all 17, that would really not be good." Garnett's got the scoop on decoding the four quadrants of 'The Red Ring' on your Xbox 360... and llamma.com has a great rundown on the error codes and how to read them....

Provide tech support for friends and family from miles away! Which is the better smart phone: the iPhone 3G or Nokia's N95? How to catch up with all your RSS feeds on your mobile phone! What the heck is causing your machine to run at 100% all the time? And how does the Bad Ass Gaming PC handle games like BioShock and Crysis?

Many of you have written in about the inability for non-US residents to win the Bad Ass Gaming PC Giveaway. Unfortunately, different countries have different rules about giveaways and related contests. Now this isn't an issue on relatively inexpensive items like t-shirts, CDs, or posters. PCs are pricey items, however, and as you know, when $$$ is involved, things get complicated with the lawyers and bureaucrats. So until we have the money and resources to do a different contest for each and every country... which we don't... it's open to the US only.

We got several replies about a question we had in Episode 45 about getting replacement OS install discs for Dell machines stating that Dell does indeed give users replacement discs for their machines. All they need to do is call customer service or submit a support request through the website.

Our freebie download this week is SiSoft Sandra Lite. A great benchmark and diagnostic tool for you Windows XP/Vista machine.

Veronica and Pat share their opinions between the Nokia N95 and Apple's iPhone 3G. It's a battle between 5MP camera phone goodness and a slick touch screen interface.

Want to provide tech support for friends and family without driving out to their house? Then you need remote admin tools. While Windows XP and Vista have these already installed and free to use, Microsoft's particular implementation can be a bit confusing. If you want open-source options check out VNC. Although solutions like RealVNC cost money others like TightVNC are free. If you just want something that even a computer neophyte can use check out GoToMyPC. The downside is that you'll need to fork over $20 a month for a subscription.

Need a way to check out how your website looks in different browsers? Then surf on over to this week's website pick: Browsershots.

Just got that sinking feeling when all your honeymoon pics on your media card bring up an error message on your PC? Well Veronica and Pat cover a couple of options for recovering that info without relying on the supernatural, including VirtualLab Data Recovery.

And if your CPU continually runs at 100% in Windows, the problem may lie with a bug in Windows – surprise, surprise – and the answer may lie in this Microsoft support page.

Our Badass Gaming PC Is Assembled! Replace Lost Windows Disks. Rescue Scratched CDs/DVDs. A Better Microphone For Your PC. Play DOS Games in Vista and XP. How to throttle your high speed internet bandwidth so everyone can get an equal share.

Is somebody hogging the bandwidth in your house? Check to see if your router offers QoS settings so you can to throttle bandwidth on your network. If you've got one of the ever so popular Linksys WRT54G broadband router that supports firmware upgrades, you can check out the advanced bandwidth throttling features in the DD-WRT or Tomato firmware.

Playing DOS games in Windows on today's machines can be a tricky affair. You can try Windows XP's compatibility mode, but running a DOSBox will probably work better. If you're a fan of the old LucasArts games like Monkey Island and Day of the Tentacle check out the ScummVM project.

This week's Freebie download pick is a pair of Free Non-Destructive Disk Partitioning Tools! We've spent the most time with GParted, great free tool for "creating, destroying, resizing, moving, checking and copying partitions, and the file systems on them," but a general hue and cry on Twitter led us to the most fabulous PartedMagic, which packs a set of useful tools around GParted!

Ready to win our Badass Monster Gaming Machine? (Sponsored by Nvidia!) We'll have the full details soon; our build a PC segment will be delayed a week as the parts we order wind their way thru the Internets. Our apologies for the delay!

CJ's angry with Patrick! He says, "Patrick is sorely misinformed if he believes that a quad core gaming system doesn't benefit from the two extra cores." Sorry, CJ, just because boutique builders can get folks to drop cash on quad core CPUs doesn't mean they help much on gaming. Check out Look at ExtremeTech's Core 2 Quad vs. the Core 2 E8500. We're building dual core for now... then, when quad core chips get cheap (and there are heaps more game that pop with quad core) we'll upgrade!

Zac wants to know which media center software he should on his Mac, and wants to know what we think of Boxee. Veronica's got a full review of this slick (and social) replacement for Front Row that works with the Apple Remote.

We want your questions on video! Just record yourself asking a question no longer than 15 seconds, upload the video to YouTube, then email us the link with "Video Question" in the subject line. (No attachments, please!)

As an added incentive.... Veronica will be giving away Boxee invites to 25 people at random who email us with VMAIL questions!

This Week's Website We Can't Get Enough Of: GetHuman.com, one of the crappiest looking and most useful websites we've ever talked about. GetHuman allows you to figure out which combination of phone buttons will connect you to an actual living, breathing person that can answer your questions!

James emails from the UK with some serious concerns about P2P privacy "It's become quite clear that the government are teaming up with ISPs in order to punish anyone caught using filesharing programs; I've heard that DNS configuration, and encryption can be quite valuable in protecting yourself online, but I'm unsure where to start."

First off, we'd love for the Tekzilla Crew to email us with their ideas about how to protect yourself online... second, we've got some questions about how useful it is to encrypt P2P traffic, but encrypting email is quite useful. Tor is great for hiding your tracks when you're online.

Daniel wants to know if he can upgrade his motherboard and CPU without reinstalling Windows.

Is that notebook burning your lap? Xander asks "Exactly what options do us laptop owners have when it comes to keeping our cool - besides moving to a colder area? I've heard about laptop cooling stands, but how well do these function?" We've got options for Xander

Devin's checked out Twitter and has one thing to say: "I don't get it." Neither did Patrick till he checked out an alternative Twitter client (like Twhirl. And, as Roger puts it, "you need a group of friends online with you. Like any social network, if you don't have people to bounce ideas, comments or topics off of it can be pretty boring."

Want to hang with us on Twitter? Come hang with Roger, Veronica and Patrick. It's weird, but we like it.

WiFi upgrade fun: 802.11n wireless router vs. an 802.11g notebook? Rob, you'll need an 802.11n WiFi card for your notebook for it to work, and, yes, it should boost the distance and speed you can connect from.

Got a question? Send us a video! All you need to do is record yourself in front a video asking a question no longer than 15 seconds. Post the video on YouTube and email us the link with "Video Question" in the subject line. (No attachments, please, post 'em on YouTube!)

Website We Just Can't Get Enough of: Pandora.com. It just might be the last music website you'll ever need... all you need to do is enter the name of an artist you enjoy!

Rob wants to protect his new phone... I can't wait for the Golden Shellback Splash Proof Coating to become a product I can buy. It's a it's a waterproof polymer that coats your electronics inside and out. As in your gear will operate underwater!

More traditional bombproofing for a an iPhone 3G? Patrick uses an InvisibleShield to protect the screen on his phone. OtterBox makes pretty bombproof cases... now we just need a YoTank for the iPod.

Heads up: starting next week, on July 19th, new episodes of Tekzilla will release on Saturday instead of Friday... same show, just on a different day. Sorry for the change!

What's the best graphics card for $200? Should I upgrade the graphics in my notebook? Is running a pair of cards in SLI worth the money? How fast is the 9800 vs. the 8800? I don't game... what kind of graphics card do I need? Will external GPUs be worth trying? You sent in a ton of great graphics card questions, ExtremeTech.com's video card mavin Jason Cross joined us to bring you the answers!

"I'm confused about the correct way to charge a battery. About half the sites I read say you shouldn't charge much, and let the battery run down, while the other half say the opposite, that you should charge often and not let the battery run down. Which way is correct?" Good question, Michael! If you don't want to kill that pricey Lithium Ion battery in your notebook, phone, iPod or whatever, follow our guidelines for charging your battery!

"Is there an email or IM service which will let me send sms text messages from my computer?" Sure are, Maxwell, and since most of the online text messaging services are web-based, it doesn't really matter whether you're on windows or mac. Veronica tested a couple, just to see what was out there and found that text'em worked best... plus it's free!

This Week's Freebie Download Pick: HoverIP, any easy way to access to all your network settings scattered around Windows XP in one easy to use control panel.

We received a few concerned emails about last week's Freebie Download AVG Free Anti-Virus, specifically, the built in Link Scanner function, and it's ability to spike traffic to unsuspecting websites... AVG has issued a patch that disables the more aggressive scanning done by Link Scanner, and says "Search-Shield will no longer scan each search result online for new exploits, which was causing the spikes that webmasters addressed with us."

This week's Website We Just Can't Get Enough of: the Home of the Underdogs, a "Tribute to the best underrated PC games of all time" that preserves and catalogs the early history of PC Gamging... right down to hosting the code for games that have fallen out of copyright and helping you run games designed for 8MHz PCs on today's 3GHz processors!

Nate wrote in "I respond to a lot of e-mails every day and most of my responses are the same. Is there a program for OS X that will allow me to reply to similar e-mails without re-writing or copying and pasting the entire email?" Veronica reccomends the legendary TextExpander, $30, which you can use to fill out forms, enter signatures, or even save whole paragraphs you can paste in when you type a short abbreviation.

Anybody know of a TextExpander-ish tool for Windows? Please email a link to: tekzilla@revision3.com and we'll share it on the show!

Jeff wants to know what the deal is with playing Bluray on his brand spankin' new MacBook Pro... there isn't a Blu-ray playback option built in!

Veronica wants to see more of your lovely faces on Tekzilla! So please please please... keep sending us your video emails. Remember make the questions no longer than 15 seconds, up load them to YouTube, and email us the linke with "Video Question" in the subject line. AND NOOOO ATTACHMENTS.

Will the security ports built into Jacob's notebook keep it from walking away if he leaves the door on his dorm room open. (No AC otherwise!) Yes... as long as the thief isn't real determined. It helps to plop it in a drawer out of site to keep 'theft of opportunity' temptation to a minimum!

A great point and shoot camera that does video, tools and techniques to bring spring cleaning to your hard drive, Roger compares some great free FTP clients: there's more difference than you might think!

Thanks everybody for writing in! We had a love hate relationship with 'em, but it's a little sad that CompUSA's retail stores are dead. CompUSA.com lives on, tho, the URL is now run by Tiger Direct.

While we're in a deathwatch kind o' mood... Analog Cell Service is dead, too. OK, technically, "cellular telephone companies will not be required to provide analog service" as of February 18, 2008... watch out for your older OnStar or alarm system cell service!

Inkscape: How does this free alternative compare to Adobe Illustrator the industry standard vector graphics editor... and just what the heck are vector and raster graphics? Our very own Pixel Princess, Stephanie Chu, aka Revision3's Interactive Designer, is here to give us the scoop!

DoD wipe? As of November 2007, the Department of Defense no longer accepts 'successive over-writes' as a means of sanitizing drives... what they will accept to wipe drives makes for an interesting read

Thanks for the heads up, Ed... btw, we agree w/ Ed, who said "I don't think users who wipe their drives clean have anything to worry about unless they think the NSA is after them :-)" Damn skippy!

BJ from Deptford, NJ is looking for a recco on computer speakers for listening to music. If money is no object, you might consider home stereo speakers (shielded, please, if you have a CRT) and a decent reciever... or Garnett's new fave sound source, the $400 Razor Mako 2.1

We found some great options for a little over $100... the Klipsch Promedia 2.1 deliver a ton of quality sound (with a rockin' low end) for as little as $120... if you don't want to deal with wiring a subwoofer (and don't need the big bass that comes with one) Creative's GigaWorks T40 are definately worth a listen.

Scott from Sound Bend, IN can't understand why there are wireless and wired print servers.... and would prefer to buy a print server that works, please. We understand that pain. Most of the networking gear in Patrick's house carries the Linksys brand, but he had a miserable experience with their wireless print servers. (He says don't buy any print server you can't return, and try to find out if the mfg supports your printer!)

Will EA release a version of Rock Band on the Wii? Yes, Benjamin, it's due to hit the shelves later this year... using Wiimotes!

Mike's new Ethernet line dies every time he tries to run it thru the wall... but laying it on across the floor, it works fine. Sounds like he's got a power line running parallel to it in that wall. You need to cross power lines at a 90 degree angle!

Yahya wants a recco on a portable music player... that delivers excellent sound quality, and maybe that isn't an iPod. First off, make sure you've got quality audio files to listen to... and a decent set of headphones. (Garnett's convinced the player is the least of your worries.)

Patrick's spent a bunch of time with the Zune and it's quite good. We've also heard good things about Creative's Zen V Plus, the oh so stylish iRiver Clix Gen 2 is a great (if pricey) follow up to the most excellent iriver Clix. If you're looking for video playback, too, the editors at Cnet are big on the Archos 605.

Why does an HDTV cost more than the same sized LCD monitor? Good question, Christopher.

Free file o' the week:

Quick Media Converter lets you drag and drop video into 13 different formats, including PSP, iPod and web friendly formats!

Turning a vertical PC case on its side and running it that way hurt it? We wouldn't worry, Benedict. Patrick's run most of his PCs in horizontal mode with no ill effects. Just don't cover the vents. (They do take up more desktop space, that way, tho!)

Dave, Michael and "B" wrote in with ideas to help Jesse get his Xbox 360 connected to the his dorm's ResNet... and Eric sent a warning that spoofing a MAC address can get you kicked out of school. (It got him tossed!)

What's a good program to format you computer Naevek? Whatever comes with the OS, Windows or OS X will work fine for partitioning a drive.

Converting FLAC files to MP3 files? No problem, John. We use dBpoweramp, tho you will have to pay for MP3 support... ya know, since you're using a Zune, you might want to go with WMA instead of MP3... you should be able to do that for free in dBpoweramp.

No soldering this week... the saws are silent. We're talking time this week to answer some of the many emails we've received about the projects we've done and will do in the coming months!

Wardriving seems to be a favorite of viewer Justin. He's been sending, no, flooding, our email servers with requests to do an "...episode of Systm on Wardriving", so Patrick has Wardriving in 60 Seconds for Justin. ;

Patrick just wishes he'd remember to suggest InSSIDer instead of NetStumbler for Wardriving on Windows... it's mucho more functional on Vista and offers some nifty features.

Patrick out in Wisconsin wants us to build a Cantenna... nothing wrong with that, but we recommends he check out EP 45: Practically Free WiFi Antennas... where we went over 3 low cost but better than stock DIY options for boosting Wi-Fi reception.

Nick was so enamored with our build a combat robot episode a few months back he wants a wiring diagram for that very design. Thankfully Dave is here to share his wisdom on the whole thing and why it's a lot simpler than you might think.

Michael had question about an alternative method to erasing your hard drive that we didn't cover in Episode 74. Is it a sure fire winner or does it a few flaws that could potentially leave him susceptible to data thieves?

Danny had a question about the noise generated by the electroluminescence sheet we used in Episode 70 and Andrew had a related question about how to go about installing an EL sheet into the back of Macbook.

Of course in every batch of email we get there are always a few that could be considered eccentric or even "odd". But since we're all about equal opportunity we decided to put in a few of the more colorful email requests we received.

Brandon is quite excited about having us dedicate a show to growing pot... in a DIY hydroponics setup... in a secret 'geek friendly' hidden room behind a false bookshelf... wired with all the connectivity any geek might need while hiding out. Pat and Dave are amused and explain what may or may not keep them from attempting it in the near future.

Finally, Thomas wants us to show him how to build... a lightsaber. Not some cheap knock-off that looks like a lightsaber but a real honest to gosh replica of a the prop lightsabers used in the Star Wars movies.

Coincidentally, Dave just happens to be one of the world's biggest Star Wars fans and freaks on the planet. How freaky? Let's see: Homemade Storm trooper armor? Check. Hand built life-size R2D2? Double-check (he has 2). Replica lightsabers? Big check... he has a complete set based on the same parts the original prop makers built for the original Star Wars.

Sharing media throughout your house isn't too hard if you have a home network... even if, like Walt, you have "3 Macs, 2 iPhones, and numerous iPods." The trick is putting all the audio/video/photos you want to share on one machine you can always leave on, then turning on file sharing. And mapping your various machines at home to it. Call it the simplest home media server possible...

Looking for music on the web? We've got nifty tools for you to check out!

Songbird is billed as a "Desktop media player mashed up with the web." We think of it more as a media browser. Built on the Mozilla application framework (the code underneath Firefox!), Songbird skims web pages for downloadable audio files when you load them, can play your local audio, and thru plugins, even manage your iPod. (And this just scratches the surface.)

Songza is pure music search. And playback. And one click posting to your website. You can even build playlists. We just can't figure out just exactly where it searches... tho we suspect it plays the audio tracks from files found in Google Video searches... you can't download the songs you find to your desktop, but there's a lot of stuff being played from YouTube thru Songza!

"Any ideas when or if Draft n will become standard?" Sure, Scott. The 802.11n spec has one last IEEE vote in early 2008, then should be finalized and on the shelves around September 2008. The years of staring at Pre-N and Draft-N on boxes is almost over... Wi-Fi Alliance certification has already begun.

Certification would be nice, since we've bought Draft n products off the shelves recently that wouldn't work together.

Do you need 802.11n? It's not going to make your Internet connection faster (not unless your existing Wi-Fi network is saturated with too many clients... rather unusual for a home setup) but, in theory, it should give you four times the bandwitch of 802.11g... which is nice for transferring big files across your network. (Gigabit Ethernet stomp it, speed wise, tho you'll have to run a cable!)

Nintendo fans have a whole new Mario experience: Super Mario Galaxy will probably be the biggest title on the Wii this season... and with 40 galaxies, gorgeous art, and a whole new style of play, it's living up to the hype.

Ex Machina, Heather's producer pick this week is one of Patrick's favorite comics, too. Penned by Brian K. Vaughan, the series follows the exploits of retired super hero Mitchell Vaughan, who was elected Mayor of New York City post 9/11. Are all his powers -the ability to communicate with and control machines- gone? Not exactly...

Code Red is where Jessica tells you about her latest obsession... this week it's FFFFOUND!.com, a neat little place on the Internet where you can post and share your favorite images. The service also has the ability to recommend images it thinks you'll like based on your interests. This isn't another Flickr clone. The makers call it "an inspirational image-bookmarking experience!!" Jessica agrees.

John needs a cheap notebook, he's a "full-time student living off water, sunshine and take-out" that needs to talk with his family overseas. We've got ideas, from a Nokia's $250 N800 Internet Tablet to the name brand notebooks showing up at CompUSA for $650 with 1.5GHz Core 2 Duo processors, 1GB of RAM and 160GB hard drives... we're talking Sony and HP here, not no brands.

One catch: you'll need an HDCP compliant graphics card and monitor to get the full HD resolution out of those pre-recorded movies. (Tho we hear you can get around that with a copy of SlySoft's AnyDVD. Email us if you're curious.

As Jessica pointed out, this isn't much of a bargain. You're paying $180 for the drive and $99 for the software (not to mention the whole HDCP ready graphics card question). You can buy Toshiba's HD-A2 for $230 at Walmart and lots of other stores. Sure, it's not the latest HD DVD Player (there's no 1080p out), but it does a pretty good job.

Google co-founder Larry Page and FCC Chairman Kevin Martin discuss the FCC's white spaces vote and Google's vision for wireless broadband connectivity at the Wireless Communication Association International conference. The event, moderated by WCA President Fred Campbell, took place on November 6, 2008 in San Jose, California.

Your router gets a major upgrade with the free Tomato Firmware: monitor bandwidth consumption, boost your WiFi signal, make major QoS tweaks, track the results with shiny graphics... and more!

I'd like to give you a project suggestion for Systm: show us the proper method for upgrading an older wireless router with ddwrt firmware.

Great idea, especially since Patrick's long suffering Linksys WRT54G has been a touch flakey after the last firmware upgrade.

We just want to make one change: DD-WRT is great, but we're more into the Tomato Firmware upgrade... it's a tad less polished looking, but has slightly better quality of service contol than DD-WRT, allows boosting your your WiFi output, and has amazing bandwidth monitoring tools, which are great to keep in mind in wake of the new Comcast cap!

It runs on Linksys' WRT54G/GL/GS, Buffalo WHR-G54S/WHR-HP-G54 and other Broadcom-based routers, and, as Wikipedia puts it, is "based on the GPL sourcecode released by Linksys, but includes proprietary binary modules from the chipset manufacturer Broadcom. Portions of the code are licensed under the GNU General Public License, but the source code for the user interface is under a more restrictive license which forbids use without the author's permission." Which is to say, it's Open Source.

Cut and past your way to better WiFi reception? It costs pennies and takes the fabrication skills of a kindergartner... then bend a 6dBi Omni and a 10dBi directional out of copper wire!

David's got a bit of trouble getting his WiFi Router signal to reach every corner of his house... one of the easiest fixes ever isn't a trip to the local computer store, but a trip to the kitchen for aluminum foil, then to the home office for a manilla folder and a glue stick.

We went to the Seattle Wireless most excellent collection Antenna HowTo for the SardineCanAntenna a biquad you can build with or without an N-connector, at least at the antenna end! (just search WiFi Biquad to find a host of construction ideas!) You don't have to use a sardine can, just about anything will work as a reflector, even a pressed CD... it just needs to be metallic and around 150mm in diameter.

There are quite a few more WiFi antenna designs out there... these are just some of our faves!

If it's got a 386 processor and 32MB of RAM, and you can find a pair of Ethernet cards, you can turn that Junk PC into a serious Firewall to protect your network.

Ah, the wonder that is IPCop... a free Open Source firewall you can run on 'junk PC' hardware.

We walk you thru the installation on this episode of Systm: It'll keep your network seriously safe.

The main trick in setting up IPCop, after, of course, you've found an old Intel/AMD/Cyrix/Via/whichever machine that still runs, is securing a couple of compatible Ethernet cards... check cards against the IPCop Hardware Compatibility List before you buy 'em!

You can download it here... we prefer the ISO version you can burn to a bootable CD-ROM, it's called "ipcop-1.4.18-install-cd.i386.iso"

Check out the documentation before you start, and definately take soem time to check out the laundry list of IPCop Add Ons you can use to customize your IPCop installation with various filters, servers and (sweet!) OpenVPN.

OK, so the Illinois State Police aren't after us. Yet. But we love that flick.. and it always reminds of us taking road trips.

Which reminds us of a recent road trip where we had three notebooks four people, and one EVDO modem... what we needed was Wireless Access in the truck. Or, as we're calling it, the Wireless Access Truck. (Props, by the way, to the StompBox, an achingly similar project we found about three hours before we started taping this show.... the onboard live tracking in that machine is way cool, tho we're going for something simpler than Tar's Pebble Linux implementation!)

We'll be removing the spaghetti wiring from Patrick's beloved truck in the next episode, dropping in the components to the Wireless Access Truck, and seeing what sharing WiFi feels like at highway speeds.

Before that we wanted to walk thru the components we're bundling together... and marvel at the simple fact than an iPhone, Blackberry, or any of laundry list of phones out on the market can do what folks wanted to do with CarPCs back in the day, like play MP3s and run mapping software, but they do it in a smaller package, and with wireless access, to boot.

Of course, Systm is about getting your DIY on, so we rustled thru the parts bin in Patrick's garage and found an 800MHz Mini-ITX machine that runs on 12V. (That means no annoying 12V from the car to 120V via an inverter... the $25 we paid for it is just a sweet bonus.)

Next week we'll be wiring up Patrick's truck which is in desperate need of some high amperage power into the cab (he regularly runs 2 50W race radios and has a 900W of power amplifiers on the way) with proper wire gauges and fusing... we'll go over that week, along with seeing how well the our DIY WAP works out on the highway!
